Problem
1. Write an assembly program to find the smallest element of an array of n 8-bit elements. The array is stored in program memory starting with the label arr-z.
2. The sign of a signed number is the most significant bit of that number. A signed number is negative when its most significant bit is 1. Otherwise, it is positive. Write a program to count the number of elements that are positive in an array of n 8-bit integers. The array is stored in bank 1 of data memory starting from 0x00.
